GUIDE-PULLEY.

Specification of Letters Patent.

Patented Mar. 24:, 1914.

To all whom it may concern Be it known that I, J OHN MURRAY, a citizen of the United States, residing at the town of Mount Vernon, in the county of Winona, State of Minnesota, have invented certain new and useful Improvements in Guide-Pulleys; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in guide pulleys for use in connection with hoisting ropes.

The invention has for its object to provide a guide pulley so constructed that it will effectually guide and prevent tangling of the hay sling hoisting rope.

A further object of the invention is to provide a guide pulley especially designed for use in round barns wherein it is necessary that the hoisting rope which leads from the hay sling frame be guided as the frame of the sling travels upon the circular track therefor.

With these and other objects in view this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which Figure 1 is a partial sectional view taken through a round or circular barn, showing the manner in which the pulleys are arranged therein. Fig. 2 is a sectional view showing one of the pulleys applied. Fig. 3 is a side elevation of one of the pulleys. Fig. L is a detail perspective view of the pulley frame. Fig. 5 is a top plan View of one of the devices. Fig. 6 is a fragmentary view showing one of the pulleys applied.

Referring to the drawing, the numeral 1 designates a section of a circular barn having the interior studs 2 and roof rafters 3, the latter serving to support the circular track 4, which is of the usual construction. To each roof rafter 3 is secured a clevis which serves to support the frame 6, said a being formed a single length of sheet frame metal so bent as to provide upper and lower plates 7 and 8, and between which are rotatably mounted the guide pulleys 9, which may be formed from metal or wood, as deslred. The upper plate 7 is partially twisted, as at 10, to provide a vertical plate 11, said plate being formed with a slot 12 for pivotally engaging the clevis 5. The plate 8 terminates at its inner end in a downwardly extending plate 13 which has a curved end 14, so that the hoisting rope 15 will be easily guided to the pulley 9.

Secured to the inner. end of the plate 7 of each frame 6 is thelower end of a chain 16, the upper ends of these chains being adapted to adjustably engage the hooks 17 secured to the roof rafters 3, so that said frame can be raised or lowered to difierent inclined relations with the said rafters.

One end of the hoisting rope 15 is connected to the hay sling frame 18, in the customary manner, said framebeing of the usual construction.

From this construction it will be seen that when the free end of the hoisting rope 15 is pulled, the same will be effectually guided and prevented from becoming tangled, as the same passes over the pulleys 9 during the movement of the sling frame 18.

What is claimed is A guide pulley comprising a frame formed from a single length of sheet metal and bent to provide upper and lower spaced plates, a pulley rotatably mounted between the plates, the upper plate being twisted at its inner end to provide a vertically dis posed late which is adapted to be pivotally connected to a support, the lower plate of the frame terminating in a downwardly extending plate, the lower end of which is curved for guiding a rope to the pulley, and a chain for connecting the frame to a support, as and for the purpose set forth.

In testimony whereof, I aifix my signature, in the presence of two witnesses.

JOHN MURRAY.
